Fourth, it is a good idea to hold it down somehow (either bolt it down, or clamp it in a vise). Old used bolts are fine – probably better than new ones!). Third, all bolts under tension (so the welder advised me, and I followed his advice) should be of the grade 5 (or higher grade) steel, and the two side bolts (holding the yoke together) should be, not only grade 5 or better, but also solid shank where the stress is (the grade of steel can be noted by the little lines on the head of the bolt. Also, the blade should be of the cold-chisel type of steel (I got the material from a wide cold-chisel that I think was really a sort of jack-hammer bit), and to get it into the holder (two bolts hold it in), the end needed welding onto a piece of softer steel, with the two holes cut in it. One is that two blades are not always necessary. There are a couple of things to note, however. Some of these show an old pipe vise fixed up to trim minerals. 1919, v4, 14-15 Developing Crystallized Mineral Specimens.

I do not have at present a rock saw (although I have materials to make one I have no experience with such), and have not considered as economical one of those expensive trimmers that have been sold for several hundred dollars each.
Peter Nancarrow, That is a sweet 'build' you put togther, NICE!Ģnd Apr 2016 18:14 UTC Dana Morong Trimming Tools, homemade It may be at the Paypal link- but I didn't check it when I replied here.ĭo be patient for reply, it may take a couple days. I am sorry I no longer have the exact details but I was VERY pleasantly surprised that the unit was nicely affordable, and the shipping from UK to USA was much less than I expected! Contact him for pricing, it is not listed on website. (My friend was just shopping at time- so I haven't gotten to play with one in person yet.) Quite nice and he knows what he is doing. Peter Trebilcock is the engineer for these~ They look to be well made. I inquired for a friend when I heard about these last year. I remember the high sticker shock of Zuber and Wards stuff when I was looking several years back so do see the link below! I have a large trimmer which I have extensive use time on, and have used a few others also.
