    WTB Bridgeport Drum Switch

    Mine, came with a Cutler Hammer drum switch. When I bought my Bridgeport mill, I changed it out. It worked just fine when I took it out. I just changed it out because I was giving the mill a referb and bought new parts for just about anything I touched. I happened to find a new one on Ebay or...

    Looking for recommendation for type of carbide inserts for boring small holes (steel-1/2") with a boring head

    Sorry for the confusion. Criterion head accepts 3/4" bars, but the bars for smaller holes neck down. The Criterion set (with the 3/4" head) goes from 1/2" to 1-1/4". Each bar is 3/4" dia. at the big end, with a flat to hold it parallel with an allen screw in the boring head. The smaller bars...

    Looking for recommendation for type of carbide inserts for boring small holes (steel-1/2") with a boring head

    I know boring bars have been discussed extensively on the forum, but I can't find any topics recommending carbide inserts for small holes. I have a Criterion boring kit with 3/4" dia. carbide faced bars, but prefer bars with carbide inserts. I have a few 3/4" bars which take either TPGB-321...

    OT: Would like advice on sizing hydraulic fittings to prevent cavitation of control valve on backhoe

    Just as a follow up, went ahead and had the hoses made 1/2" and 1/2" quick connects. If the machine has issues, I'll probably just add another block of remotes with larger quick connects. Thanks again for all the helpful comments on this thread. Always appreciate the collective technical...

    OT: Would like advice on sizing hydraulic fittings to prevent cavitation of control valve on backhoe

    Thank you. I hadn't actually checked the flow rates of the couplers, until just now. It would make sense to me the quick connect coupler Pioneer type (iso 5675) would have more restriction than the JIC fittings. The tractor and my other equipment all have 1/2" Pioneer quick connects, which...

    OT: Would like advice on sizing hydraulic fittings to prevent cavitation of control valve on backhoe

    Again some good comments, and food for thought. Thank you. The tractor has an open center system. The backhoe is also set up for open center, but can be switched to closed center with a little bit of minor re-plumbing. The tractor is capable of 14.5 gal/min, but that is at max PTO speed and...

    OT: Would like advice on sizing hydraulic fittings to prevent cavitation of control valve on backhoe

    Thanks for the replies. I really appreciate the comments. To answer some questions. I completely agree pipe threads are the devil in sealing higher pressure oil lines. Especially Chinese threads. They are horrible. To my embarrassment, I've bought Chinese threaded fittings/pipe before...

    OT: Would like advice on sizing hydraulic fittings to prevent cavitation of control valve on backhoe

    Background: I recently bought a Bradco 509B attachable backhoe. It was made in 2019, but has never been used. The company has discontinued manufacture of attachable backhoes and customer support has been disappointing. I did not purchase it from a dealer, so there is no dealer support either...

    OT: Arm Wrestling Table Design Question

    Follow up - arm wrestling table Two of the legs on each side are welded together to make a sort of C shape, which still fits into a car. They are connected with a cross member which is again bolted to the two sets of legs by way of more 1/2"- 13 button head cap screws. I keyed one side of the...

    OT: Arm Wrestling Table Design Question

    Follow up - Arm wrestling table Sorry for resurrecting this old thread, but wanted to post a follow up and ask a couple more questions. I finally got some time this winter to build the arm wresting table. It turns out there are some table specs outlined by the World Arm Wrestling Federation...

    Clearance question on stuffing box gland?

    Btw, If bronze is recommended for the gland, what type of bronze would be most suitable? Probably a dumb question, but I'm assuming bearing bronze? Also what type of joint would be recommended to fit the flange and cylinder together (i.e. press fit, butt braze, press and braze)?

    Clearance question on stuffing box gland?

    Thanks very much for the helpful information. That's actually very close. I haven't measured the pulley assembly, but I'd estimate the 1.2" SS shaft turns at about 120 rpm. Thanks for that. That's exactly some of the info I was looking for. I do notice that the new stuffing box has a...

    Clearance question on stuffing box gland?

    Build question stuffing box gland I had another question regarding this stuffing box gland, if anyone has any thoughts on this? I plan to make a new one, instead of repairing the current one with a bushing. The current one has some grease grooves which would be hard to replicate using a...

    Putting a Machine Shop in a Cargo Container

    I have a couple 20' High Cube shipping containers I keep things in. For my equipment 20' is much more manageable to move. I prefer the "one trip" containers. They aren't as dented. Floors aren't rotted. Paint is better looking. They have the newer enclosed lock boxes. Prices are very high...

    Clearance question on stuffing box gland?

    Thank you very much. One other question if you please. Is it generally the case that the minor diameter of the stuffing box is the same as the minor diameter of the gland? If this is the case, I would know the exact size to bore the hole in the bushing to repair the gland. Here drawing of...

    Clearance question on stuffing box gland?

    I have a stuffing box on a piece of equipment which needs replaced. It's a simple brass stuffing box with string packing and a brass gland. A new one is not available. I'd like to put a bushing in the worn gland, but I don't know the clearance required between the gland and the SS shaft...

    OT: Arm Wrestling Table Design Question

    Thanks to everyone for the ideas. I knew I'd get a lot of good design concepts from this group. I like the ease of the pipe and couplings. But the ideas of legs with a taper fit sound pretty good too. And there were some good ideas for bracing. Thanks again to all.
