Lathe Rest wont stay up

[Bart430]

The lathe rest on my new Mk 7 wont stay in the up position. The table height lock wont get tight enough. It works fine with the table but the lathe rest slides down with pressure. Thanks

I don't do a lot of turning so I am not speaking from experience! However, if the table height lock works (as you have said) but does not work when using the lathe rest, I would first determine if the post on the lathe rest is the proper size. What are the dimensions of these two different "posts"?

My two table legs measure 1.2375" and 1.2365". The post for the lathe rest measures 1.2380". My table height locks quit reliably. I can only assume that the lathe rest would too. However, there two legs being locked versus only one which might make a difference.

The table legs on mine are 1.237 and 1.238. The lathe rest leg is 1.228. I guess I could wrap tape on the leg and see if it holds but that isnt a permanent fix.
