Re: 123 blocks


 

Thanks for that reference. Will read it later. Been looking for something like that. Anyway, just to clear some things up, the lms blocks have the unthreaded holes are all large enough to fit the bolts in. The threads are good also. But on the one block, when they tapped the holes for the required threaded holes, the tapping process left ears or pieces of metal sticking into the unthreaded hole. These pieces are small. I do understand that they cannot be drilled nor tapped. So my only option is to grind them off. This may turn out to be impossible.? I'm actually amazed at how many are made so poorly considering its rather a simple process. I have watched and read about the more expensive ones and they all are made so that the bolts can fit into the untapped holes. But for sure, I'm not spending that kind of money for my little shop. So tell I can deal with that issue I will be using that kit that was mentioned. So I will inform you all if I do get the block up to snuff. Silence means i have had no luck.
Thanks all for the help,

george

George,

You might want to have a quick look at ? to understand why they are made the way they are (and each manufacturer is different).

Good Luck,

Yea, I bought that kit at the time I ordered the original blocks from amazon. I basically knew that the unthreaded holes dont always allow the threaded boots to go through but still thought I would be able to do something or get lucky. Almost made it with the lms set but only got one good block. Not making them that way just makes no sense. Well, to me.?

which is designed to be used on the import blocks which I have never found to have a usable thread or clearance hole.

If you purchased imported 123 blocks it¡¯s a hit n miss.? If you¡¯re looking for perfect 123 blocks you¡¯ll need to spend some extra money and get them from a reputable manufacturer like Starrett or similar.? The other option is to run a tap through the thread holes to clean them up.

Have A Great Day??

How about talking 123 blocks. I'm a bit at a loss about them. Or the basic manufacturing of them and what's expected. I bought one set on amazon and it was awful.? Couldnt even screw in a bolt. Retuned it. Then ordered a kit from lms. One block was perfect for me, I could insert the supplied bolts into every hole. Bolts threaded in nicely in the threaded holes. But the other block I could not insert the bolt into any of the unthreaded holes. I contacted lms and got the we will call you back message. Left a message but never recieved a call back. So much for customer service. Anyway I thought I could use a grinding stone to open them up. But after two broken stones and one burnt out fuse on my dremel I'm at a loss. Anything on these issues would be appreciated.
