Current (2008-2011...) Model 375 Manual

Model 375 Universal Cutter Grinder Service Manual. (Kenosha, WI: Famco Machine Division of Belco Industries, 2008.) I obtained my copy of this manual directly from Famco as the current version of the manual, in July 2011. The cost was $75. It is a substantial revision of the former manual. It does not bear a Gorton-style 4-digit "form number"; it is identifiable only by its title, its copyright dates (2004, 2005, 2006, 2007, 2008) and its length (v + 42 pages). The version supplied by Famco appears to be a printout of a scan of the manual. (They offered to supply it either electronically or on paper; in retrospect I should have chosen the electronic version and simply printed it out myself.)

This is both a grinding instruction manual and a nominally illustrated parts list. It is much better than the earlier "Form 2006-A" (see below), but it still has issues. It does name the parts in the parts list (2006-A does not), but the drawings (clearly scans of copies of old drawings that were probably very nice when drawn decades ago) are murky at best; important parts on them cannot be distinguished. It does not give instructions for the disassembly of the workholding head. It does not give specifications of the tapers used for the wheel spindle or the workholding head. (In fact, despite its title, it provides little real service instruction at all.) The names used for parts in the instruction section do not necessarily correspond to the names of those parts in the parts list. It does, however, briefly discuss lubrication, which is nice. It shows the 717-7 workholding head and a guard-mounted diamond dressing attachment (which was not present on machines the vintage of mine).

This manual is in copyright and is not reprinted here. (The icon-size reproduction of its cover for purposes of identification should, I think, be within the limits of "fair use" under US copyright law.)

Form 2006-A. Instructions, Cutter Grinder 375

Grinding Instructions for Gorton 375 Cutter Grinder. (Famco Division of Belco Industries) This document seems to have been developed by Lars Machine, Inc. (inside the covers, there is no reference to any company beyond Lars), which would place its composition in the period 1974/5 - 1987. The copy I have, though, seems to have been published later, in new covers, after Lars was acquired by the Famco division of Belco in 1987. It is not a very good manual.

This manual is in copyright and is not reprinted here. (The icon-size reproduction of its cover for purposes of identification should, I think, be within the limits of "fair use" under US copyright law.)

Form 2842-C

Form 2842-C. This is the grinding instruction manual for the 375 cutter grinder with the 717 tool head, in its 1964 version. 16pp. I've not yet seen this document; some sources online are selling photocopies of it for astonishing prices.

Note that there are important differences in the construction of both the wheel spindle nose and the method of retaining the workholding sliding spindle on this generation of machine when compared to later machines such as the 375-4 that I have.

Gorton "Form 2508," reproduced on www.gorton-machine.org/forms/index.html, is a pair of photographs showing an unidentified tool or gauge for the model 375 cutter grinder. It also gives a nice view of the older style of the 717 Universal workholding head for the 375.

(And it shows an almost unbelievably cool sight-feed oiler!)
